摘　　要：以大豆油酸为原料,经α-氯代、酯化、成盐、肟化、酸化等单元反应合成了一种新型季铵盐羟肟酸磷矿浮选捕收剂,用于湖北某中低品位(P2O517.09%)硅钙质磷矿石的正反浮选工艺的研究。结果表明,相对于传统的脂肪酸类磷矿浮选捕收剂,该捕收剂的水溶性好,浮选性能得到明显改善,且原料易得,价格便宜。Using soybean oleic acid as raw material, a novel quaternary ammonium hydroxamic acid phos- phate flotation collector was synthesized by chlorination, esterification, salification, oximation, acidification. Ap- plied to the flotation test for a low-grade （P2O5 17.09%） silicon-calcium collophane ore from a mine in Hubei, this collector showed better solubility and collecting capacity than traditional fatty acid phosphate flotation col- lector. Meanwhile,the raw material could be easily accessed at low price.
